Description Kaj J. Niemi 2004-06-10 11:24:41 EDT
Description of problem:
dmesg/syslog fills up with multiples of the following:

Unknown EII protocol 86DD: csum at 16
Unknown EII protocol 86DD: csum at 16
Unknown EII protocol 86DD: csum at 16

Protocol 0x86DD is ethernet content type for IPv6. And I do have IPv6
running and working fine along with IPv4. This only started happening
with rather recent kernels.

Version-Release number of selected component (if applicable):
kernel-2.6.6-1.422

How reproducible:
Always

Steps to Reproduce:
1. Boot normally
2. dmesg or less /var/log/messages
3.
  
Actual results:
Unknown EII protocol 86DD: csum at 16
Unknown EII protocol 86DD: csum at 16
Unknown EII protocol 86DD: csum at 16

Expected results:
Be silent. :-)

Seems to have started May 25th with 2.6.6-1.381.

Comment 2 Arjan van de Ven 2004-06-11 02:35:24 EDT
can you give a list of the modules you're using? This message seems to
not come from the core kernel

Comment 4 Arjan van de Ven 2004-06-11 05:34:23 EDT
does this reproduce without the vmware modules loaded ?
Comment 5 Kaj J. Niemi 2004-06-11 05:37:36 EDT
I'll check
Comment 6 Kaj J. Niemi 2004-06-11 05:37:51 EDT
Forgot all about them ;(
Comment 7 Kaj J. Niemi 2004-06-11 19:14:54 EDT
It is not vmware's fault. My VPN connection wasn't enabled at the time
I did lsmod. The problem maker is cisco_ipsec provided from Cisco's
VPN Client 4.0.4 (A). It works like a packet interceptor and does not
support IPv6 at all.

My bad, should have opened a TAC ticket instead.
